Abstract:By means of the design procedure of a column in a project, the design concept of steel tube-reinforced concrete column is presented. During the shaping process of the column, measures of strengthening,combining,constraining and superposing different materials of which the column is consisted are taken to achieve the target of optimum column cross section. In addition, the technical economy and optimizing design target for the steel tube-reinforced concrete column are analyzed and discussed.
